On one particular site, CKEditor behaves rather weird:
When I copy and paste "normally", i.e. CTRL + V, there is an alert popping up "do you really want to leave this page?". If you cancel, the text is pasted into the field. If not, you get redirected to the frontend of the page you just edited, and the changes are lost.
The "paste from Word" button doesn't work. CTRL + SHIFT + V works, but all formatting is lost (apart from paragraphs).
I'm using inline editor mode, ACF + Purifier are activated. I know that if I disable those two, CTRL + V works, but I won't do that, since CKE then saves all the garbage code from MS-Office.
Has anyone ever come across this issue? I tried with Chrome + FF. No JS errors.
